Error when try to turn on a nonwiki forum to a wiki forum one

[stev]

Hi,

In Forum manager, I choose "Enable Wiki in this forum?" and also YES on "Automatically create links to relevant wiki pages?"

Got this error:

The forum could not be added to the namespace. Create the forum with the Wiki mode disabled, and configure the namespace in the Namespace Manager to include this forum. You can then activate the forum's Wiki mode.

I am running 3.0.0 Beta 6

What do I need to do to fix it?

Unless you want it to be an Island wiki, the wiki forum has to be a child forum of an existing wiki forum. If you want it to be in a new namespace, then you should create the namespace first.
